Healthcare utilisation (HU) is key to improving the health of residents in urban informal settlements. This study aimed to explore household-level factors influencing HU among informal settlement households in Freetown, Sierra Leone.
Cross-sectional survey.
Three informal settlements (Cockle Bay, Dwarzark and Moyiba) in Freetown, Sierra Leone.
Primary data from 4871 households were collected during the Health and Wellbeing survey conducted between April and May 2023, targeting households with adults aged 18 years and older.
The primary outcomes were households HU both within and outside informal settlements. Household-level predisposing and enabling explanatory variables were derived from Andersen’s Behavioural Model of HU.
Disability in households increases HU within settlements (especially in Dwarzark, 13% and Moyiba, 10%) but is less likely outside. Households engaged in income-generating activities are more likely to seek healthcare within settlements, but 12% less likely outside in Cockle Bay and Dwarzark. Food insecurity decreases HU within Dwarzark (9%) and increases HU outside by 174% in Moyiba. Longer water fetching times and water shortages were associated with higher HU (between 6% and 16%) within settlements, especially in Cockle Bay and Dwarzark. Clean water sources (eg, piped dwelling, bowser, surface, bottled) were consistently associated with higher HU both within and outside settlements. Shared sanitation facilities (such as shared toilets) were positively associated with HU both within and outside settlements, particularly in Dwarzark and Moyiba. Households with income from fishing, informal salaried work and bike riding showed higher HU both within and outside settlements, especially in Dwarzark and Moyiba.
We identified strong settlement-specific patterns of household-level factors that influence HU both within and outside Freetown’s informal settlements. These findings provide a foundation for developing targeted policies such as strengthening local services, addressing affordability and accessibility barriers and supporting vulnerable occupation groups.
The debate about whether health visiting, a specialist community public health nursing role, is at the level of advanced practice nurse has gone on for more than a decade. There is little empirical evidence that the role matches the traditional role of an advanced practice nurse, although many of the attributes of advanced practice nursing such as prescribing rights, managing complex cases, caseloads with undifferentiated need and advanced assessment and decision-making are certainly present.
The current study aimed to develop, refine and test the Health Visiting Advanced Practice Scale to assess the scope of advanced practice of UK health visitors.
A cross-sectional and methodological scale validation design, following classical test theory.
The design consisted of three phases; the first involved scale development including item generation, phase two assessed the content validity index, and the third phase involved a cross-sectional survey to establish construct validity, content validity, and internal consistency reliability, and conduct exploratory and confirmatory factor analysis.
The initial 44-item scale underwent iterative exploratory and confirmatory factor analyses, leading to a refined 5-factor structure with 29 items covering domains such as family-centred care, leadership, prescribing, diagnostic reasoning, and professional practice. This final version demonstrated strong reliability and construct validity in the EFA but mixed fit indices in the CFA, supporting both internal consistency and validity of the scale.
The final scale offers a rigorously validated tool for assessing advanced practice among UK health visitors, capturing core domains such as family-centred care, leadership, prescribing, and diagnostic reasoning. By bridging theoretical frameworks with real-world practice, it fills a critical gap in evaluating and supporting the professional scope of this public health nursing specialty.
These findings provide valid and reliable insights for measuring and improving health visitors' advanced practice and developing future professional policies.

The aim of this study was to identify the clinical factors associated with postoperative visual acuity following Descemet’s membrane endothelial keratoplasty (DMEK), with emphasis on the impact of macular diseases. This retrospective multicenter study included consecutive eyes that underwent DMEK between March 1, 2011, and June 30, 2022, and had available optical coherence tomography findings. Eyes with other ocular diseases causing visual loss were excluded. Overall, 77 eyes of 66 patients were included in the study. Univariable and multivariable regression analyses were performed to identify the predictors of best-corrected visual acuity (BCVA) at the final follow-up. Worse preoperative visual acuity and macular comorbidity were identified as independent predictors of poorer postoperative BCVA. Among macular pathologies, cystoid macular edema was most strongly correlated with reduced vision in the univariable analysis (β = 0.195; p = 0.016). In the subgroup analysis, worse preoperative visual acuity and macular comorbidity remained significant predictors (pby Seong Tak Woo, Sungdae Na
Intraoral palatal plates used in electropalatography (EPG) and tongue-interface systems are designed to monitor articulatory movement with minimal disruption to speech. However, their presence may subtly influence acoustic characteristics by altering tongue mobility and intraoral airflow. This study examines the acoustic effects of a pseudo-palatal plate during the articulation of consonants and vowels. Speech samples from healthy adults were recorded with and without the plate and analyzed using spectral and phonatory measures, including Mel-frequency cepstral coefficients (MFCCs), second formant (F2) slope, jitter, shimmer, harmonics-to-noise ratio (HNR), and quadrilateral vowel space area (qVSA). MFCC-based correlation coefficients and F2 slopes remained highly consistent across conditions, indicating minimal impact on consonant articulation. Shimmer (−0.72%), HNR (+2.5 dB), and qVSA (−24.1%) exhibited directionally consistent changes, with qVSA trending toward reduction; however, overall variation was limited. Vowel formant structures and consonant production were preserved mainly, suggesting that the palatal plate did not significantly impair vocal function. These findings support the interpretation that observed acoustic shifts are more consistent with filter-level effects than with changes at the glottal source. Although palatal plates may introduce minor acoustic variations, their impact on speech production appears minimal, reinforcing their suitability for therapeutic and assistive use, provided that acoustic considerations are addressed during design and clinical implementation.The second phase of the Chiba Study of Mother and Child Health (C-MACH) was initiated to investigate how environmental exposures from the fetal period to early childhood influence maternal and child health outcomes. The sub-cohort focuses specifically on detailed assessments of indoor environmental factors and neighbourhood-built and social environments. By integrating environmental metrics with biological, behavioural and sociodemographic data, the study aims to elucidate their role in the development of allergies, neurodevelopmental disorders and other non-communicable diseases in early life.
Between June 2021 and April 2023, 505 pregnant women were enrolled in the second phase of the C-MACH main study. Of these, 298 participants consented to join the sub-cohort study, including 258 in the sleep and physical activity monitoring option (Option 1) and 148 in the indoor allergen exposure sub-study (Option 2). The study includes biological sampling, environmental monitoring and repeated questionnaire surveys. At baseline, 253 live births were recorded from 251 pregnancies.
Of the 298 women, 272 completed early pregnancy questionnaires. The mean maternal age was 33.1 years (SD 4.6); 97.8% were married. University-level education was reported by 51.0% of mothers and 53.7% of fathers. Most households had an annual income of 6 to
Longitudinal follow-up will continue until the children reach age 15. Future analyses will examine associations between environmental exposures and allergic, developmental, endocrine/metabolic and obesity-related outcomes.
Non-communicable diseases are the leading causes of premature mortality worldwide. Both genetic predispositions and environmental exposures affect disease risk. While biobanks have increased understanding of genetic predictors of these diseases, environmental influences are expected to have a greater impact on disease development. Individuals also create their own environments and lifestyles based on genetically regulated preferences, leading to gene–environment interactions that require large datasets to study. Finnish biobanks typically lack sufficient lifestyle and environmental data, which limits their use. We present a protocol for a biobank-recall study (BioRecall) to collect data on lifestyle and environmental exposures and combine these findings with genotypes, biological samples and clinical outcomes.
All previously genotyped donors from the Central Finland Biobank who have been diagnosed with type 2 diabetes and have consented to recall will be invited to participate in the pilot study. The preliminary feasibility assessment reveals that there are 1580 suitable candidates. Participants will complete an electronic questionnaire on a secure online platform. The questionnaire includes validated questions on lifestyles, anthropometrics, weight loss history, health, symptoms, work characteristics, emotional states and residential environments. Postcode information will facilitate the addition of spatial environmental data. Genotype and related clinical data will be provided in the study in accordance with the Finnish Biobank Act and combined with questionnaire data.
The Human Sciences Ethics Committee of the University of Jyväskylä delivered a favourable statement regarding the study protocol (1671/13.00.04.00/2023). Central Finland Biobank approved the research plan (no: BB24-0333-A01). The data collected will be returned to the Central Finland Biobank for research purposes with the participants’ consent. Permission for data usage can then be applied through standard protocols of the Fingenious service (https://site.fingenious.fi/en/). If successful, the study will be expanded to other donors and Finnish biobanks.
Oxaliplatin, a key drug in the treatment of colorectal cancer (CRC), can cause oxaliplatin-induced peripheral neuropathy (OIPN) in a dose-dependent manner. These symptoms can severely affect daily life, and chronic OIPN often limits treatment continuation because of its correlation with the cumulative dose of oxaliplatin. Currently, effective preventive measures are unavailable. However, surgical glove compression therapy may reduce paclitaxel-induced neuropathy, suggesting its potential in preventing OIPN.
This multicentre, randomised, open-label, phase II/III trial evaluates surgical glove compression therapy to investigate the possible preventive effects of OIPN in patients with CRC receiving adjuvant capecitabine plus oxaliplatin chemotherapy. Patients with stage III CRC undergoing curative surgery will be enrolled and randomised into two groups. The intervention group will wear two layers of tight-fitting surgical gloves from 30 min before to 30 min after oxaliplatin infusion, whereas the control group will receive standard care. The primary endpoint is the incidence of grade ≥2 chemotherapy-induced peripheral neuropathy (CIPN) based on the Common Terminology Criteria for Adverse Events criteria. Secondary endpoints include quality of life assessments (Functional Assessment of Cancer Therapy/Gynecological Oncology Group-Neurotoxicity-12 and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20-item), duration and extent of OIPN as assessed using the Debiopharm Neurologic and Sensory Toxicity Criteria, chemotherapy completion rates, and adverse events. To detect a significant reduction in the incidence of CIPN, 170 patients will be enrolled (36% in the control group vs 15% in the intervention group). The planned case enrolment period is from 1 November 2024 to 31 October 2026.
This trial was approved by the Institutional Review Board of Hiroshima University, Japan (approval no. CRB2024-0008), and has been registered with the Japan Registry of Clinical Trials (jRCTs062240066). The results of this study will be submitted for publication in a peer-reviewed journal and shared with the scientific community at international conferences.

Positive aspects of caregiving among family carers of persons living with dementia not only benefit the carers' health, but also enhance the quality and sustainability of invaluable informal care resources. To better inform the development of carer support intervention to optimise positive aspects of caregiving, this paper tested the integrative theoretical model based on stress coping and meaning-making paradigms.
Longitudinal exploratory study.
From January 2018 to August 2021, 390 Chinese family carers of persons living with dementia were recruited from the geriatric clinics in Hong Kong. The criterion variable was measured by the Positive Aspect of Caregiving Scale at baseline and 6 months thereafter. The predictors were measured using the Dementia Management Strategies Scale, the Caregiving Self-Efficacy Scale, the Meaning-Focused Coping Scale, the Medical Outcome Study Social Support Survey, the Duke University Religion Index, the Positive Affect Index and the Intrinsic Motivations to Care. Path analysis tested the hypothesised model.
The carers aged 56.2 (SD = 12.2); about two-thirds being female and adult-child caregivers. The hypothesised model showed an unsatisfactory model fit. The model was optimised by modification index with consideration of the theoretical plausibility in making the changes (CFI = 0.971, RMSEA = 0.057, SRMR = 0.027). After adjusting the baseline PAC, the 6-month PAC was predicted by self-efficacy in controlling upsetting thoughts and obtaining respite as well as meaning-focused coping. Various contextual factors strengthened the self-efficacy and meaning-focused coping, indirectly increasing PAC. Whereas carers' intrinsic motivation towards care and good dyadic relationships increased the carer's self-efficacy in emotional regulation, social support and religiosity played indispensable roles to facilitate meaning-focused coping.
PAC in dementia context is evolved from an integration of stress coping and existential meaning-making paradigms. Enhancing emotion and role regulation as well as meaning-focused coping are crucial to enhance the positive experience of the family carers.
This project has generated a theory-driven and evidence-based predictive model to explain the manifestation of positive aspects of caregiving in dementia caregiving. The findings provide precise directions on how to empower family caregivers to create a fulfilling and meaningful caregiving adventure.
Substantial evidence indicates the role of positive aspects of caregiving in enhancing the carers' health outcomes in the context of dementia. However, inadequate theorization of this phenomenon delimits the momentum to develop proactive strategies to optimise such a positive caregiving experience. This longitudinal study indicated that positive aspects of caregiving are evolved from an integrative stress coping and existential meaning-making paradigm. More specifically, a sense of self-efficacy in emotional and role regulation as well as the use of meaning-making coping predict a higher level of positive aspects of caregiving. A context, which is characterised by high religiosity, good intrinsic motivation of care and a good dyadic relationship, also favours the cultivation of this positive experience during life adversity. This study facilitates a paradigm shift in supporting family carers in a dementia context and advances the theorization of positive human experience in facing life adversity.
The reporting method complies with the STROBE, stands for observational study.
Family carers of persons with dementia actively shared their experience in family caregiving.
Nurse migration remains a significant issue in global healthcare, often driven by economic incentives, work environment factors, and professional development opportunities. Greece's prolonged economic crisis and low nurse-to-population ratios have further intensified the outflow of skilled nursing personnel. We aimed to examine how demographic, educational, and professional factors, along with working conditions and perceived challenges, influence Greek nurses' motivation to migrate after the COVID-19 pandemic.
This quantitative study surveyed 121 Greek nurses–both employed and unemployed, from various regions.
Structured questionnaires featuring closed-ended, Likert-scale, and open-ended items were used. Questions covered demographics, working conditions, migration motives, and perceived challenges. Data were analysed using Pearson's Chi-Square, Likelihood Ratio tests, and correlation coefficients, with statistical significance set at p < 0.05.
Economic prospects, quality of life, and access to language support emerged as key “pull” factors. Conversely, family obligations, emotional attachments to Greece, fear of discrimination, and inadequate language skills served as barriers to migration. Age and marital status both shaped participants' attitudes; younger nurses were generally more optimistic about overseas opportunities, while those with multiple children expressed greater reluctance. Increased computer literacy and higher education correlated with reduced concerns, and leadership responsibilities were linked to heightened caution about relocating.
Findings underscore the complexity of nurse migration decisions. Policymakers and healthcare institutions should consider providing enhanced career development, language support, and better working conditions to retain Greek nurses and mitigate the impact of ongoing workforce shortages.
This study highlights critical factors influencing nurse migration, informing policies to improve retention and address workforce shortages in Greece.
Participants provided insights on migration motives, enriching understanding of healthcare workforce dynamics and informing policy development for retention.
High costs of screening and diagnostic tests remain a major barrier to timely tuberculosis (TB) identification in resource-limited settings. Evidence on the cost-effectiveness of scalable screening algorithms is limited. Start4All is a research project aimed at developing and evaluating algorithmic approaches to TB screening and diagnosis, with the goal of optimising technical and allocative efficiency when expanding diagnostic coverage to primary healthcare and community settings.
Five screening and diagnostic tests will be evaluated: a capillary blood-based assay (C-reactive protein (CRP)), sputum-based rapid molecular tests (PCR; individual and pooled Xpert MTB/RIF Ultra assay (Xpert Ultra, Cepheid®, California, USA)), a lateral-flow urine-based test for lipoarabinomannan (LF-LAM), and digital chest X-rays with artificial intelligence-based computer-aided detection (CXR-CAD). A microbiological reference standard of positive culture using the mycobacteria growth indicator tube will be used to confirm TB disease.
We will compare the cost and effectiveness of concurrent and sequential positive serial combinations (screening algorithms) of CRP, CXR-CAD, LF-LAM, individual and pooled Xpert Ultra. Diagnostic performance will be estimated using sensitivity, specificity, predictive values and proportions of positive results, with Bayesian inference used to derive these estimates. The analysis will include adults (15 years and older) only and will be stratified by HIV status and level of care, including facility and community-based case finding. Effectiveness will be assessed based on the number of people with TB detected. Cost analysis will be conducted from the provider perspective, incorporating commodity and implementation costs. A decision tree model will be developed to assess the cost per number of persons with confirmed TB detected across all countries. Probabilistic sensitivity analysis will be conducted to account for uncertainty in model parameters, incorporating willingness-to-pay and willingness-to-accept thresholds.

BackgroundOccupational low back pain (LBP) has increased in Japanese social welfare facilities and hospitals. Understanding its occurrence is the first step in addressing this issue.
AimThis study investigated the caregiving activities that cause occupational LBP incidents in these contexts.
MethodsThe study analyzed 2,722 incidents of occupational LBP among staff in social welfare facilities and hospitals resulting in four or more days absent from work. Data were extracted from accident occurrences and causes in the 2018–2019 Reports of Worker Casualties. The caregiving situations related to the occupational LBP incidents at each facility were then analyzed.
ResultsApproximately half of the occupational LBP incidents surveyed occurred during transfer assistance. This assistance was mainly associated with eating, bathing, and toileting in both facilities and frequently occurred during patient transfers between a bed and a wheelchair. In social welfare facilities, nontransfer assistance also contributed significantly, which included bathing, toileting, childcare, diaper changing, lying, standing, sitting, walking, and car transportation. In hospitals, nontransfer assistance such as providing support for lying, diaper changing, medical care, and sitting were occupational LBP risk factors. Furthermore, most incidents of occupational LBP occurred among staff who worked alone during day shifts.
ConclusionCaregiving activities involving transfer assistance, such as bathing, toileting, and eating, were common risk factors in social welfare facilities and hospitals. However, the specific nontransfer assistance activities contributing to occupational LBP varied by facility. To effectively reduce the incidence of occupational LBP, prevention strategies should focus on these high-risk activities according to facility type and the types of caregiving required.

AimThe underlying mechanisms contributing to cholestatic liver injury remain unclear. The pro-inflammatory leukocyte-restricted cytokine interleukin-17A (IL-17A) has been implicated in human cholestatic liver injury. However, mechanistic insights are lacking and require further exploration in preclinical models. Herein, we examined the effect of IL-17A genetic ablation in a mouse model of cholestatic liver injury.
MethodAge and gender-matched littermate wild type (WT) and Il-17a-/- C57BL/6 mice were fed an intermittent 0.1% 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet for 21 days to induce cholestatic liver injury or a control diet.
ResultsAs compared to WT littermates, Il-17a-/- mice displayed more abundant desmin-positive myofibroblasts and increased fibrosis. NanoString analysis of intrahepatic leukocyte populations using a fibrosis-related gene panel identified upregulation of Tnfsf14 (encoding the protein LIGHT) in the DDC-fed Il-17a-/- mice. Although mass cytometry identified an increase in myeloid cells in both genotypes of the DDC-fed mice, we could not identify LIGHT expression in this cell lineage. Instead, the upregulation of LIGHT expression was largely restricted to a CD4+ T cell population as assessed by flow cytometry. Enhanced LIGHT expression was observed in a Th1+ CD4+ T cell population. LIGHT activated primary human hepatic stellate cells in vitro, suggesting that LIGHT stimulation of hepatic fibrogenesis may be direct.
ConclusionTaken together, these data suggest that IL-17A restrains expression of the profibrogenic cytokine, LIGHT, by Th1-polarized CD4+ T cells, and implicate a role for LIGHT in cholestatic fibrogenesis in DDC-fed mice; a finding which requires validation in additional models.
To examine the relationship between weight loss and problems with oral intake in institutionalised older adults.
A 1-year longitudinal observational study.
Data were obtained from a prospective study conducted in three nursing homes and two long-term care facilities in Japan. Participants' problems with oral intake were assessed using items published in 2021 by the Japanese Ministry of Health, Labour and Welfare. Baseline and follow-up factors were compared between individuals who experienced a weight loss of 5% or more and those who did not. Separate multivariable logistic regression models were constructed for each oral intake assessment item to examine its independent association with weight loss of 5% or more, accounting for transitions in each item between baseline and the 1-year follow-up.
In total, 172 institutionalised older adults were included in the analysis. Among them, 57 (33.1%) participants experienced a weight decrease of 5% or more. The emergence of somnolence or clouding of consciousness during meals at the 1-year follow-up in participants without these signs at baseline was independently associated with a weight loss of 5% or more, after adjustment for baseline characteristics.
Recognising signs of somnolence or clouding of consciousness during meals may be useful for the early detection and prevention of weight loss in institutionalised older adults.
Early detection of individuals at risk is essential to prevent significant weight loss and its associated adverse outcomes. Recognising somnolence or clouding of consciousness during meals may enable earlier detection and intervention to prevent weight loss and improve the quality of care for older adults.

Medication administration errors are high-risk patient safety issues that could potentially cause harm to patients, thereby delaying recovery and increasing length of hospital stay with additional healthcare costs. Nurses are pivotal to the medication administration process and are considered to be in the position to recognize and prevent these errors. However, the effectiveness of interventions implemented by nurses to reduce medication administration errors in acute hospital settings is less reported.
To identify and quantify the effectiveness of interventions by nurses in reducing medication administration errors in adults' inpatient acute hospital.
A systematic review and meta-analysis was conducted up to 03/24. Six databases were searched. Study methodology quality assessment was conducted using the Joanna Briggs Institute (JBI) critical appraisal tools, and data extraction was conducted. Meta-analysis was performed to combine effect sizes from the studies, and synthesis without meta-analysis was adopted for studies that were not included in the meta-analysis to aggregate and re-examine results from studies.
Searches identified 878 articles with 26 studies meeting the inclusion criteria. Five types of interventions were identified: (1) educational program, (2) workflow smart technologies, (3) protocolised improvement strategy, (4) low resource ward-based interventions, and (5) electronic medication management. The overall results from 14 studies included in meta-analysis showed interventions implemented by nurses are effective in reducing medication administration errors (Z = 2.15 (p = 0.03); odds ratio = 95% CI 0.70 [0.51, 0.97], I 2 = 94%). Sub-group analysis showed workflow smart technologies to be the most effective intervention compared to usual care. Findings demonstrate that nurse-led interventions can significantly reduce medication administration errors compared to usual care. The effectiveness of individual interventions varied, suggesting a bundle approach may be more beneficial. This provides valuable insights for clinical practice, emphasizing the importance of tailored, evidence-based approaches to improving medication safety.

BackgroundThe interaction between viral components and type 1 or type 2 cytokines during asthma exacerbations in the airway epithelium may contribute to worsening inflammation. However, these interactions in the small airway epithelium—particularly those involving alarmins (TSLP, IL-25, and IL-33) and IL-8—remain unclear. Dupilumab, a biologic agent used in severe asthma, blocks IL-4 receptor alpha (IL-4Rα) and may offer therapeutic benefits in virus-induced asthma exacerbations. In this study, we evaluate the effects of double-stranded RNA (dsRNA), in combination with various cytokines and dupilumab, on the Human Small Airway Epithelial Cells (HSAECs) line.
MethodsPrimary HSAECs were preincubated with dsRNA to induce the gene and protein expression of alarmins and IL-8. To evaluate the effects of cytokines on dsRNA-induced alarmin and IL-8 expression, various type 1 and type 2 cytokines were co-stimulated with dsRNA. Dupilumab was used as a pretreatment prior to co-stimulation with dsRNA and IL-4 or IL-13. Gene expression of TSLP, IL-25, IL-33, and IL-8 was assessed by quantitative PCR, and protein expression was evaluated by Western Blotting.
ResultsdsRNA significantly increased the expression of TSLP and IL-8. IL-4 and IL-13 further enhanced dsRNA-induced TSLP and IL-8 gene and protein expression. In contrast, TNF-α reduced dsRNA-induced TSLP expression but enhanced IL-8 gene and protein expression. Dupilumab attenuated the expression of TSLP and IL-8 induced by co-stimulation with dsRNA and IL-4 or IL-13 in HSAECs.
ConclusionIn the microenvironment of small airway epithelial cells, particularly during viral infections, the presence of IL-4 or IL-13 may enhance the expression of TSLP and IL-8. Dupilumab attenuates this expression, potentially offering additional benefits in the treatment of asthma, especially during virus-induced asthma exacerbations.
In 2017, the Japan Diabetes Society and Japan Geriatrics Society published the Clinical Practice Guidelines for the Treatment of Diabetes in older adults, marking a major shift in glycaemic management policy for older adults. The guidelines represented a transition from conventional, uniform targets, originally developed for the general adult population, to stratified glycaemic goals tailored to the complex care needs of older patients, including comorbidities and frailty. Although the 2017 guidelines aimed to promote individualised care and reduce adverse events such as severe hypoglycaemia, the real-world impact on patient outcomes, clinical practice and healthcare expenditures has not been evaluated at the national level.
A population-based interrupted time-series analysis will be conducted using data from the National Database of Health Insurance Claims of Japan, which captures nearly all insured healthcare encounters nationwide. This study will include individuals aged ≥65 years with diabetes who received insurance healthcare services between April 2016 and June 2019. Outcomes will be evaluated across three domains: patient outcomes, clinical practice and healthcare expenditures. Specifically, these will include the incidence of severe hypoglycaemia, acute coronary syndrome, hyperglycaemic emergencies such as diabetic ketoacidosis and hyperosmolar hyperglycaemic state, number of antidiabetic prescriptions and total healthcare expenditures. Primary analyses will use generalised linear mixed-effects models assuming Poisson or negative binomial distributions with adjustments for facility-level heterogeneity. Stratified analyses will be performed according to comorbidity burden, frailty status and receipt of relevant healthcare services. Sensitivity analysis will assess the robustness of the results using an alternative definition of severe hypoglycaemia.
This study was approved by the Ethics Committee of the National Centre for Geriatrics and Gerontology (No. 1752), and the need for informed consent was waived owing to the use of anonymised administrative data. These findings will be disseminated through peer-reviewed publications and presentations at international academic conferences.
Older adults with cancer have ageing-related vulnerabilities that influence their treatment tolerance and decision-making. In our previous randomised controlled trial (MAPLE), integrating geriatric assessment (GA) with communication support using a question prompt list (QPL), delivered by trained intervention providers, facilitated patient–oncologist communication, increased implementation of GA-guided management (GAM) and improved patient outcomes. However, its widespread adoption has been limited by the need for trained personnel and dedicated time. To enhance scalability and sustainability, we developed a mobile application-based intervention to deliver GAM and communication support. This MAPLE2 study aims to evaluate the feasibility of the intervention using this mobile application-based GA and QPL among older adults with cancer.
This multicentre, open-label, pilot randomised controlled trial will be conducted at two academic hospitals in Japan. Patients aged≥70 years with solid cancer or lymphoma initiating or changing systemic therapy will undergo baseline GA. Patients with any GA impairment will be randomised to receive either (1) a mobile application-based intervention providing feedback of GA summary with tailored GAM recommendations and QPL or (2) usual care. The primary endpoint is the proportion of participants who complete all of the following interventions using the mobile application: (1) self-administered GA, (2) receipt of the tailored GAM recommendations and QPL and (3) confirmation that their oncologists review the tailored GAM recommendations and QPL at subsequent visits. Forty participants are planned to be enrolled.
The study has been approved by the Institutional Review Board of the National Cancer Center, Japan (approval number: 2025-089). Written informed consent will be obtained from all participants. Results will be presented at academic conferences and published in peer-reviewed journals.
Recruitment has been initiated from 8 September 2025 and is planned to be completed by 31 August 2026, with a follow-up period by 31 August 2027.

BackgroundIn tropical to subtropical regions, centipede bites may prompt medical attention, with manifestations largely reflecting venom-related discomfort, although infections, including rare fatal necrotizing soft tissue infection (NSTI), have been reported. However, no reports are available on the commensal bacteria on centipede forcipules.
ObjectivesThis study aimed to investigate bacterial species residing on and in centipede forcipules and their potential role in post-bite infections.
MethodsNine Scolopendra mutilans, three Scolopendra japonica, and two Bothropolys rugosus were collected from three regions in Japan. The bacterial composition of their forcipules was analyzed using 16S ribosomal ribonucleic acid gene sequencing and microbiome analysis.
FindingsA diverse bacterial community was observed on the centipede forcipules. Among the NSTI-associated genera examined (Escherichia, Staphylococcus, and Streptococcus), only Staphylococcus was identified as a minor population.
ConclusionThis study provides the first evidence that some bacteria found on centipede forcipules have been previously isolated from centipede bite infections. The risk of infection from bacteria on centipede forcipules during a centipede bite appears low. However, the presence of diverse bacterial species emphasizes the importance of thoroughly cleaning centipede bite wounds to prevent secondary infection.
To assess nutrition-related knowledge, attitudes and practices among pregnant women, and identify socioeconomic and healthcare determinants.
A cross-sectional study on maternal nutrition during pregnancy.
Pregnant women attending primary healthcare centres in the south of Tehran from December 2022 to March 2024.
1535 pregnant women of all ages living in the south of Tehran (both Iranian and non-Iranian).
Pregnant women were systematically selected from primary healthcare centres. Data were collected via validated questionnaires and electronic health records. Statistical analyses included multivariate logistic regression (adjusted ORs (aORs) with 95% CIs) and generalised linear mixed models.
The findings revealed that a majority of pregnant women (83.3%; 95% CI 81.2% to 85.3%) exhibited low levels of nutritional knowledge (scores below 12), whereas 14% demonstrated moderate knowledge (scores between 12 and 17), and only 2.7% (95% CI 1.9% to 3.8%) possessed high nutritional knowledge (scores above 18). In terms of attitudes, 36.9% of respondents expressed positive views toward nutrition, with higher education significantly associated with positive attitudes (aOR=1.8; 95% CI 1.3 to 2.5, comparing higher vs lower education levels). Dietary variety was consistently reported by 65.4% of participants, while 8.5% lacked dietary variety. Statistically significant associations were observed between educational attainment, socioeconomic status and nutrition-related practices (p
As a cross-sectional study, these findings highlight substantial gaps in nutrition knowledge among pregnant women in Tehran, with socioeconomic status and education playing crucial roles in shaping dietary behaviours. Improving nutritional education through healthcare interventions is essential for enhancing maternal and fetal health outcomes.
Treatment failure remains a major challenge in tuberculosis (TB) management. Rapid and objective assessment of treatment response is essential, as existing tools have limited accuracy and slow turnaround times. The PATHFAST TB LAM Ag assay (PATHFAST-LAM), an automated chemiluminescent enzyme immunoassay, was developed to quantify lipoarabinomannan (LAM) in sputum within 1 hour. Previous studies have shown a strong correlation between sputum LAM concentration and culture-based bacterial load. However, its clinical utility for predicting poor outcomes during treatment has not been prospectively evaluated.
We will conduct a prospective longitudinal study enrolling newly diagnosed, bacteriologically confirmed patients with pulmonary TB at Rhodes Chest Clinic and Mbagathi County Referral Hospital in Nairobi, Kenya. We will follow participants throughout the 6-month treatment course, attempting to collect sputum weekly during weeks 1–4, biweekly during weeks 5–12 and monthly during months 3–6. We will measure LAM concentrations at these time points using the PATHFAST-LAM assay. The primary outcome is to assess whether changes in sputum LAM concentration during the intensive phase (baseline to week 4 and/or week 8) predict a composite poor outcome, defined as positive sputum culture at month 6, treatment failure, death during treatment or relapse within 3 months after treatment completion. The primary endpoint is the area under the curve from the receiver operating characteristic analysis, representing the predictive performance of changes in sputum LAM concentration for the composite poor outcome. We will identify the optimal cut-off value for LAM change and estimate sensitivity and specificity with 95% CIs using 2x2 tables. We will apply an adaptive design that allows sample-size re-estimation after interim analysis.
The study was approved by the Kenya Medical Research Institute (KEMRI/SERU/CRDR/124/5241) and Nagasaki University (250619327). Findings will be disseminated through peer-reviewed publications and scientific meetings.
